+# Background Animation Optimization
+
+## Overview
+Replaced the GPU-intensive Continuous Aurora Background Animation with a more efficient, lightweight background system to improve performance and reduce GPU usage.
+
+## Changes Made
+
+### 1. Aurora Background Component (`src/components/ui/aurora-background.tsx`)
+**Before:**
+- Heavy blur effects (blur-[100px], blur-[120px], blur-[90px])
+- Continuous 60-second linear animations with `animate-aurora`
+- Complex gradient animations with background-position changes
+- Multiple layered animated elements with pseudo-elements
+- GPU-intensive transform3d and will-change properties
+
+**After:**
+- Static gradient base with subtle color transitions
+- Minimal animated overlay with gentle movement
+- Optional subtle particle effects using CSS-only animations
+- Significantly reduced GPU usage
+- Maintained visual appeal with better performance
+
+### 2. CSS Animations (`src/app/globals.css`)
+**Removed:**
+- `@keyframes aurora` - Complex background-position animation
+- `.animate-aurora` - GPU-intensive animation class
+
+**Added:**
+- `@keyframes gentle-shift` - Subtle gradient movement (20s duration)
+- `@keyframes float-slow` - Gentle particle floating (15s duration)
+- `@keyframes float-delayed` - Delayed particle animation (18s duration)
+- `@keyframes float-gentle` - Rotating particle animation (22s duration)
+
+### 3. Tailwind Configuration (`tailwind.config.js`)
+**Removed:**
+- `aurora` keyframe definition
+- `aurora` animation class
+
+**Added:**
+- `gentle-shift` keyframe and animation
+- `float-slow` keyframe and animation
+- `float-delayed` keyframe and animation
+- `float-gentle` keyframe and animation
+
+## Performance Benefits
+
+### GPU Usage Reduction
+- **Before:** Continuous GPU layer creation with transform3d and will-change
+- **After:** Minimal GPU usage with simple transform and opacity changes
+
+### Animation Efficiency
+- **Before:** Complex background-position animations running every frame
+- **After:** Simple transform and opacity animations with longer durations
+
+### Visual Quality
+- **Before:** Heavy blur effects causing rendering overhead
+- **After:** Clean gradients with subtle movement maintaining visual appeal
+
+### Battery Life
+- **Before:** High GPU usage leading to increased power consumption
+- **After:** Minimal resource usage improving battery life on mobile devices
+
+## Technical Details
+
+### New Animation Properties
+- **Duration:** Longer animation cycles (15-22 seconds) vs. previous 60-second continuous loop
+- **Easing:** `ease-in-out` for smoother, more natural movement
+- **Delays:** Staggered animation starts to create organic movement patterns
+- **Opacity:** Low opacity values (0.1-0.5) for subtle visual effects
+
+### Browser Compatibility
+- Uses standard CSS transforms and opacity changes
+- Compatible with all modern browsers
+- Respects `prefers-reduced-motion` settings for accessibility
+
+### Reduced Motion Support
+The existing reduced motion support in `globals.css` continues to work:
+```css
+@media (prefers-reduced-motion: reduce) {
+  .animate-aurora {
+    animation: none;
+  }
+  * {
+    animation-duration: 0.01ms !important;
+    animation-iteration-count: 1 !important;
+    transition-duration: 0.01ms !important;
+  }
+}
+```
+
+## Testing Results
+- ✅ Homepage loads with new efficient background
+- ✅ Results page displays correctly with new background
+- ✅ Visual appeal maintained while reducing GPU usage
+- ✅ Animations are smooth and subtle
+- ✅ No performance degradation observed
+
+## Migration Notes
+- No breaking changes to component API
+- Existing `AuroraBackground` component usage remains the same
+- All pages using the component automatically benefit from the optimization
+- No additional configuration required
+
+## Future Improvements
+- Consider adding user preference for animation intensity
+- Implement performance monitoring to track GPU usage improvements
+- Add option to completely disable animations for maximum performance
